FLOOD-FENCE..

SPECIFICATION forming part of Letters Patent No. 446,111, dated February10, 1891. v

Application filed October 14, 1890. Serial No. 368,116. (No model.)

To all whom it may concern:

Be it known that we, DANIEL E. CAssEL- MAN and ELIsIIA H. FLETCHER,citizens of the United States, residing at Evening Shade,vin the countyof Sharp and State of Arkansas, have invented certain new and usefulImprovements in Flood-Fences; and we do declare the following to be afull, clear, and exl Our invention is described as follows: IVesecureacross-tie A on a number of stringers a. In the downstream edge of thecross-tie A are recesses a', in each of which is set a coil-spring a2,(so low that when the comb is bent down said springs will be under saidcomb,) one end of which spring is attached to a downstream-brace a3, andthe other end is secured to the comb B, which is pivoted in the arms b,which in turn are attached to the cross-tie A.

Comb B is provided with a number of perpendicular teeth b', the front orupstream edges of which are beveled (see Figs. l and 3) to offer aslittle resistance to the water as possible.

C are upstream-braces, the lower ends of which are slightly notched andattached to the cross-tie, as shown in Fig. 2, and so that their upperedges will be ush with the side of the comb when the same is presseddown by the stream, and being attached in this manner they protect thebackbone of the comb B from dbris and the like that may happen to becoming down the stream.

At the free ends of braces C, braces as, and stringers a are providedperforations through which are driven stakes cc in the manner as shown;also, to increase the tirinness of this fence rock or other analogoussubstance may be placed under the braces C and a3 and over the stringersa.

Our invention operates as follows: It is placed in the bed of a streamand secured as described. When the water is at its ordinary height, thecomb will remain in an upright position; but when the Water rises thecomb will bend down under the weight of any dbris that is in the streamand it Will pass over it without injury to said comb. NVhen 'the Waterfalls, the springs a will raise the comb B back into an uprightposition. p

Having described our invention, what We claim as new, and desire tosecure byLetteIs Patent, is- ,l

1. A Hood-fence consisting of the cross-tie A, having the recesses c',the comb B, pivoted on the top of said cross-tie, springs a2, seated insaid recesses, as shown, and holding said comb in an upright position,stringers a and braces a3, holdingsaid cross-tie in place, and Yupstream-braces C, secured to said cross-tie and having their upperedges flush With the side of the comb when the same is pressed down,substantially as shown and described, and for the purposes set forth.

The combination of the stringers a, crosstie A, secured vto saidstringers and having 'the end recesses d downstream-braces a3 secured tosaid cross-tie, coil-springs a2, seated in said recess, as shown, armsb, secured to each end ot' said cross-tie, comb B, pivoted in said armsand having the front edges of its teeth beveled, upstream-braces C,secured to said cross-tie so that their upper edgesare flush with theside of said comb When the same is pressed down, substantially as shownand described, and for the purposes set forth. In testimony whereof Weallix oursignatures in presence ot' two witnesses.
